rotating a cutting die required for production to the lowest position;
3) Aligning;
manually or automatically adjusting the rotating shaft to enable the table surface of the rotating table to be flush with the working table surface of the upper working table;
the synchronous device acts to adapt the opening of the clamping mechanism to the specification of the cutting die;
4) Shifting;
sliding the angle adjusting mechanism to one side of the upper workbench through the T-shaped groove until one side of the cutting die, which is close to the upper workbench, is connected with the cutting die clamp; disassembling a bolt on the cutting die, and moving the cutting die to the lower part of the upper workbench;
5) The clamping mechanism is fixed;
the pneumatic motor acts to move the cutter mold clamp upwards to tighten the cutter mold.
